Description

Technical Field

[0001] The present application relates to the technical field of DC panel equipment, and specifically to a DC panel power supply housing. Background Art

[0002] The DC panel in the power distribution room is mainly responsible for converting AC power into DC power and storing it in the battery pack for emergency use. It also provides a stable DC power supply for switchgear and other equipment. The role of the DC panel in the power system is indispensable, and its importance is reflected in many aspects. First, the DC panel can ensure that the power system can still maintain operation and control functions through the DC power stored in the battery when the AC power is interrupted. Second, the DC panel provides the necessary high current for the closing mechanism of the high-voltage switch, ensuring the reliable execution of the circuit breaker operation. Third, the DC panel also has the important task of providing a stable DC power supply for relay protection and automatic devices. Fourth, in some emergency situations, the DC panel serves as an emergency power supply to support the power supply of critical loads such as emergency lighting loads.

[0003] The battery packs for the DC power panel are housed in a dedicated power box. This box is a housing with multiple layers of partitions arranged from top to bottom. Each layer houses a battery pack, which is then connected in series using wires. However, due to the small distance between the upper and lower partitions and the fact that only the front of the box has an access window, accessing the battery packs during wiring is difficult. Furthermore, the battery packs for the DC power panel in existing power boxes are placed directly on the partitions without being secured, making them unstable in the event of an earthquake or other emergency.
